Plain-English summary
A 7-year-old neutered male domestic shorthair cat was brought in because he had been limping on his right front leg for a long time. The vet found a cystic bone lesion in the lower part of his right upper arm (humerus) and decided to perform an amputation to remove the affected area. After surgery, the tumor was identified as an osteoblastoma, which is a rare, benign bone tumor. The cat recovered well after the amputation and is expected to live a normal life without the tumor.

Abstract
A 7-year-old neutered male domestic shorthair cat was presented with chronic lameness in the right forelimb. A cystic bony lesion was identified in the distal right humerus and amputation was performed. The epiphyseal trabecular bones of the capitulum and trochlea was replaced by a tan to pink, expansile mass that was surrounded by a thin rim of cortical bone. Microscopically, the tumour was composed of a bland, osteoid producing spindle cell population within a well-vascularized fibrous stroma. Radiographical and histological features were consistent with osteoblastoma. Osteoblastoma and the related osteoid osteoma are uncommon, benign osteoblastic tumours that are reported rarely in animals. These tumours should be considered as differential diagnoses for slow growing, cystic bony lesions in cats.
